- 3 043 734 FILING DEVICE AND METHOD OF OPERATION Robert W. Porter,Rockford, Ill., assignor to John Green Press, Inc., Rockford, 111., acorporation of Illinois Filed Mar.:6, 1956, Ser; No. 569,841 1 Claim.(Cl. 156-249) .This invention relates'to a filing device and method ofoperation, the invention being herein illustrated as em- 7 bodied in anew and improved report folder especially designed and adapted for usein hospitals and clinics,

a protective backing to keep it fresh and clean, and when the adhesiveis to be used the backing'is stripped off, the adhesive having a greateraffinity for ordinary unglazed paper than for the glazed stock used inthe backing.

A salient feature of the present invention is the provision of a folderor carrier sheet having a portion of one side thereof covered with thisspecial gummed stock, the backing or protective covering sheet beingserrated transversely to provide tear strips which may be removed oneafter another as the report sheets are to be applied, using the adhesivetransferred onto the folder and uncovered as each strip of backing isremoved, therest of the backing that is left serving as a lineup guidein the application of one sheet after another into the folder, so that aseries of sheets of the same size, as in this case of laboratoryreports, will be disposed in alignment and evenly overlappedrelationship and present a very neat appearance, and the informationcontained on any one of the sheets may be easily and quickly referred toif the lower edge portion of each sheet that is left exposed is suitablylabeled, as for example, in the case of laboratory reports with titlessuch as Chemistry, Blood count, Hematology, -X-ray, etc.

The invention is illustrated in the accompanying drawing, in which- FIG.1 is a perspective view illustrating the application of adhesive to afolder from a roller in a coating machine; 1

FIG. 2 shows on a smaller scale the next step in I perspective ofapplying the backing sheet, which may be done also by machine;

FIG. 3 shows on the same scale :as FIG. 1 the next step in perspectiveof serrating the backing sheet, which is an operation done in a press,this step being also indicated partly in section and partly in sideelevation in FIG. 4;

FIG. 5 is a perspective view similar to FIG. 2 showing a finished reportfolder ready for use;

FIG. 6 indicates'in a perspective view on the same scale as FIG. 3 howthe individual strips of backing may be removed to uncover the adhesive;

FIG. 7 is a sectional view indicating how the sheets are applied oneafter another into the folder in accordance with my improved methodusing the adhesive that is exposed when the strip has been removed, andusing the rest of the backing as a guide in the application of thesheets, and

FIG. 8 is a perspective view similar to FIG. 5 showing how a folderappears when partly filled. with report sheets or the like.

The same reference numerals are applied to corresponding partsthroughout the views.

3,043,734 Patented July 10, 1962 Referring to the drawing, the referencenumeral 10 designates a filing device comprising a paperboardv folder orcarrier sheet of the usual medium thickness used for files to the innerside of one half of which is applied a layer of pressure sensitiveadhesive or glue, as indicated at 11 in FIGS. 1 and 2. This may beapplied in a coating machine in any suitable or preferred manner, aroller for application thereof being indicated at 12 in FIG. 1,

the folders being fed automatically through the machine,

one at a time, to have the band 11 of adhesive applied thereto by theroller. Then a backing or protective covering sheet 13 of glazed paperthat is wider than the band 11 is applied immediately, extending thefull length of the folder, as indicated in FIG. 2. The marginal edgeportions 14 of the glazed paper are therefore left unattached, so thatwhen the folders are fed, one at a time, into a press for the cuttingthrough of the backing 13 on parallel lines 15 by means of a series ofparallel knifeblades 16 to define separable tear strips 17, these stripsmay be easily picked up at their ends and stripped off, one at a time,to uncover a narrow strip of adhesive to be usedin applying a reportsheet 18 by its one edge portion into the folder. The strips 17 being ofglazed paper and the adhesive 11 having a greater aflinity for theunglazed paper or cardboard 10, there is no likeli hood of the adhesivebeing stripped off when the strips 17 are removed.

In operation, after the adhesive 11 has been applied to the inner sideof the folder 10 its full length, a backing or protective covering sheet13 of glazed paper is applied the full length covering the adhesive.Then, all but one end portion .19 of an appreciable length is serratedalong the lines 15, the purpose being to use an end portion 19 of thebacking sheet 13 as a shield over the end portion .of the band 11 ofadhesive so that the first report sheet 18 that is applied when thefirst strip 17 is removed will wad-here to the folder 10 only along itsupper edge portion 20. In the application of the upper edge portion 20the edge of the neighboring tear strip 17 serves as a guide, as shown inFIG. 7, to insure the application of each report sheet 18 with its upperend at right angles to the longitudinal edges of the folder 10, and, ofcourse, after one or more other report sheets have been put in, theseserve also as a guide in the application of other report sheets later tohave all of the sheets aligned properly with one another. The lower edgeportions 211 of the sheets 18, when a series of sheets of the same sizeare used, are exposed to a uniform extent, as illustrated in FIG. 8, andin the case of hospital or clinic report folders, these marginal edgeportions may be labeled, as indicated at 22, with identifying titlessuch as Chemistry, Blood count, Hematology, Urinalysis, X-

' ray, etc., so'that information relative to the patient,

whose name may be conveniently applied to the tab 23, is quickly andeasily available. A folder with a series of these sheets neatly insertedpresents a very nice appearance and with the facilities provided inaccordance with my invention, a great deal of time is saved in thecompiling of reports on each patient and there is no danger of animportant report getting lost once it has been put in properly inthefolder. The cost of these folders, due to the simplicity and economy ofthe construction, and the fact that all of the operations requiredin'the manufacture thereof can be done in automatic machines alreadyavailable, is very low considering the advantages obtained.

It is believed the foregoing description conveys a good understanding ofthe objects and advantages of my invention. The appended claim has beendrawn to cover all legitimate modifications and adaptations.
